Nutrients with soil?

Hey friend, I've seen my plants do well for about 2 weeks before I needed to add nutrients into the mix. I would still ph my water for the 2 weeks though. You can use any brand of nutrients with that soil but if you're going to use fox farm I'd start by getting their trio of micro/grow/bloom(big bloom/grow big/ tiger's bloom). But I'd also have a cal-mag supplement, either their gringo rasta one or any brand will do. I think you can get by on just those 4 things and then any others you might add would just be extra. They have a decent feeding schedule on their website too for a guide with soil or soiless growing. Happy growing ✌️
